Abstract (en)
[origin: EP3173439A1] Carbodiimide is added to a molten polyamide resin so as to provide resin pellets. The percentage of residual unreacted carbodiimide to each resin pellet is 0.03% to 0.33% by mass. Manufacturing molded articles using the resin pellets achieves both of an improvement in mechanical strength and an increase in wear resistance, and reduces property variations among the molded articles.
